Re: [gmx-users] Still "GB parameter(s) missing or negative for atom type 'C'" issue after 7 years
Hi, The answer is still the same - if gbsa.itp has the right contents, is it being included at the right time?

Re: [gmx-users] Still "GB parameter(s) missing or negative for atom type 'C'" issue after 7 years
Hi Mark, Thanks for your hint regarding the order of itp files. I got it running now. Here's my solution for all other users (as well as for myself in 7 years again). I had an ligand itp file generated with "acpype -a amber -i ligand.pdb" in order to have the upper case atom type notation. At the top of that itp file, a first section [ atom types ] lists all relevant atom types. Some of these types are already included in the amber force field's gbsa.itp in the corresponding amber force field directory in gromacs/top. These atom types can be safely removed from the atom types section of the ligand.itp file. For those atom types of the ligand that are not listed in gbsa.itp, it was not helpful to use the corresponding atom type lines from ligand.itp. In my case this resulted in a segmentation fault. My work-around was to add these few types to a local copy (important due to reordering of itp files later!) of gbsa.itp by copying the parameters from respective atom types already existing in gbsa.itp with most similar properties (sp2/3, 1/2 membered ring, ring junction, etc.). Strangely, I additionally needed to keep exactly one of these manually added atom types in my ligand's atom types section. Finally, I still had to reorder include lines in my top file in the following way: #include "amber99sb-ildn.ff/forcefield.itp" [ atomtypes ] ;name bond_type mass charge ptype sigma epsilon Amb CD CD 0.0 0.0 A 3.39967e-01 3.59824e-01 ; 1.91 0.0860 #include "gbsa-local.itp" #include "protein.itp" #include "ligand.itp" Obviously, I had to remove the atomtypes section from ligand.itp directly into the top file and between the inculde force field line and the ligand,itp file o make things work. I hope this helps someone out there struggling with similar problems.
